SECTION 4: First aid measures

Description of necessary first-aid measures

If inhaled

Move the victim into fresh air. If breathing is difficult, give oxygen. If not breathing, give artificial respiration and consult a doctor immediately. Do not use mouth to mouth resuscitation if the victim ingested or inhaled the chemical.

Following skin contact

Take off contaminated clothing immediately. Wash off with soap and plenty of water. Consult a doctor.

Following eye contact

Rinse with pure water for at least 15 minutes. Consult a doctor.

Following ingestion

Rinse mouth with water. Do not induce vomiting. Never give anything by mouth to an unconscious person. Call a doctor or Poison Control Center immediately.

Most important symptoms/effects, acute and delayed

This is an organophosphate pesticide. Extremely toxic: probable oral lethal dose in humans is 5-50 mg/kg, between 7 drops and 1 teaspoonful for 70 kg person (150 lb.). The material is a cholinesterase inactivator. Even traces of the vapor cause pinpoint pupils. (EPA, 1998)

Indication of immediate medical attention and special treatment needed, if necessary

Since thermoregulatory disturbance may itself contribute to the morbidity and mortality in individuals exposed to cholinesterase inhibitors, and since this may be independent of the effect of the toxin on cholinesterase activity, treatment should be instituted to correct hypothermia as well as to combat cholinergic stimulation directly.

SECTION 5: Firefighting measures

Suitable extinguishing media

Fire Fighting: Self-contained breathing apparatus with a full facepiece operated in pressure-demand or other positive pressure mode. Parathion

Specific hazards arising from the chemical

May burn but will not ignite readily. Container may explode in heat of fire. Fire and runoff from fire control water may produce irritating or poisonous gases. Forms hydrogen fluoride in presence of moisture; decomposes in water at pH about 2.5. Keep away from sources of heat. Anhydrous compounds or oil solutions are stable in glass containers at room temperature. (EPA, 1998)

Special protective actions for fire-fighters

Wear self-contained breathing apparatus for firefighting if necessary.

SECTION 6: Accidental release measures

Environmental precautions

Prevent further spillage or leakage if it is safe to do so. Do not let the chemical enter drains. Discharge into the environment must be avoided.

Methods and materials for containment and cleaning up

Decontamination may be achieved by using soap washings followed by alcohol-soap washings with tincture of green soap.

SECTION 10: Stability and reactivity

Reactivity

Forms hydrogen fluoride in presence of moisture; decomposes in water at pH about 2.5.

Chemical stability

Anhydrous cmpd or oil solutions are stable in glass containers at room temperatures.

Possibility of hazardous reactions

Organophosphates, such as ISOFLUORPHATE, are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides. Isofluorphate also reacts with water to generate hydrofluoric acid, which can cause severe chemical burns and is one of the few materials that can etch glass. Fluoride is quite reactive, acting as a weak base and participating in some unique reactions. In particular, fluorides react strongly with compounds containing calcium, magnesium, or silicon ions, which means that solutions containing soluble fluorides are corrosive to both living tissue and glass.

Persistence and degradability

Microbial cell-free extracts were found to contain lysase enzymes capable of hydrolyzing diisopropyl fluorophosphate(1). This indicates that intact microorganisms in the environment may also be capable of biodegrading diisopropyl fluorophosphate. One study reported that Pseudomonas melophthora could degrade diisopropyl fluorophosphate in the presence of yeast extract, mannitol, and acetone(2). Diisopropyl fluorophosphate was found to be rapidly degraded (no quantitative rate was given) in ruminal fluid(3), which contains anaerobic microorganisms.

Bioaccumulative potential

An estimated BCF of 1 was calculated for diisopropyl fluorophosphate(SRC), using an estimated log Kow of 1.13(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low.

Mobility in soil

Using a structure estimation method based on molecular connectivity indices(1), the Koc for diisopropyl fluorophosphate can be estimated to be 31(SRC). According to a classification scheme(2), this estimated Koc value suggests that diisopropyl fluorophosphate is expected to have very high mobility in soil.

Other adverse effects

no data available

SECTION 13: Disposal considerations

Disposal methods

Product

The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.

Contaminated packaging

Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
